CFA: stands for “Chartered Financial Aanalyst”. For more information, visit the CFA Institute.

Coase theorem: if trade in an externality is possible and there are no transaction costs, bargaining will lead to an efficient outcome regardless of the initial allocation of property rights. In practice, obstacles to bargaining or poorly defined property rights can prevent Coasian bargaining.

Collectively Exhaustive: where information is being grouped into categories, all categories taken together are said to be “collectively exhaustive” if all relevant information falls into one or more categories.

Comparative Advantage: a country has a comparative advantage in producing a good if it can produce that good at a lower opportunity cost than any other country.

Debt: a form of financial leverage which can be used to increase your ability to consume or invest.

Discouraged worker: a person who does not have a job and is available to work but who has stopped actively looking for work. This may happen because an unemployed person:

  • becomes discouraged due to previous unsuccessful attempts to obtain work;
  • believes (reasonably or not) that there are no jobs available in their industry or location;
  • lacks the skills needed for the jobs which are available, either because they never had the required skills or because their skills have eroded due to a long period of unemployment;
  • is discriminated against by prospective employers for some reason beyond their control (e.g. age, race, gender); or
  • becomes addicted to Twinkies and day time television. This one sounds like a joke, but it is conceivable that after a period of prolonged unemployment a person who previously had an aversion to receiving welfare payments could become welfare dependent.

Diseconomies of scale: a situation where the average cost of production increases as output increases. For more information, read the article: Economies of scale.

Disruptive innovation: a process by which a product or service initially takes root in simple applications at the bottom of a market and then consistently moves ‘up market’, eventually displacing established competitors.

When externalities exist, the market price of the good or service will not reflect the full social cost or benefit.

Fiscal Policy: government policy as it relates to government spending and taxes.

Fixed cost: a cost that do not vary with the quantity of output produced.  It is important to understand that fixed costs are fixed only in the short term.  In the long run nearly all costs are variable: a company can renegotiate its supply contracts or move its factories to a country with lower costs of production.

Joint production: production where the production process for two or more different goods is connected. Producing the goods separately would result in increased costs. Joint production may occur naturally: for example, a chicken farm produces both chicken wings and chicken breasts. Joint production may also be used because it provides economies of scope.

Lateral diversification: a situation where a company moves beyond the confines of the industry to which it belongs. Sometimes referred to as “conglomerate diversification”.

Leverage (investment definition): the use of borrowed capital to partially or fully fund an investment. Leverage is used when an investor expects the return on investment (ROI) to be greater than the cost of debt, in which case the investor’s return on equity (ROE) will be greater than the ROI.

MECE: mutually exclusive, collectively exhaustive.

MECE analysis: the idea that, when analysing a business problem, issues should be divided into groups so that each grouping is separate and distinct (mutually exclusive), and all groups taken together should comprehensively represent all of the issues related to the problem at hand (collectively exhaustive). For more information, read the article: MECE Framework.

Mortgage Securitisation: a process which involves three steps:

  1. purchasing mortgages from banks and mortgage brokers;
  2. grouping these mortgages together into large pools; and then
  3. selling “shares” in these mortgage pools to investors.

Network effects: the situation whereby a product or service becomes more valuable as more people use it (also known as network externalities). One example is eBay; as more buyers use the online auction site it becomes more valuable to each seller, and as more sellers use the site it becomes more valuable to each buyer.

NINJA Loan: any loan made where the borrower has No Income, No Job, and No Assets.

Nominal value: a value expressed in dollar terms. For example, if a Big Mac costs $3 this year and $6 next year, then we would say that the nominal price of the BigMac has doubled.

NPV (net present value): The net present value of an investment is the present value of the series of cash flows generated by the investment minus the cost of the initial investment. For more information, read the article: Analysis Framework: Net Present Value.

Numéraire: an economic term which refers to “the unit of account”. In French, the term means “money”, “coinage” or “face value”. A country’s currency normally acts as the numéraire and is used to measure the worth of other goods and services within the country. In the absence of currency, you could define a “numéraire good” (e.g. salt, copper, gold) to have a fixed price of 1; the worth of other goods and services can then be measured relative to the numéraire good.

Oligopoly: a situation where a market is dominated by a small number of suppliers for a particular good or service. Oligopolies are characterised by a lack of competition and a lack of viable substitutes. Each firm in an oligopoly must take into account the likely actions and reactions of other firms when developing its strategic plan.

Opportunity cost: the opportunity cost of an item is what must be given up to obtain that item.

Option: a derivative financial instrument which grants its owner the right, but not the obligation, to purchase or sell an underlying asset at a pre-established price for a specified period of time.

For more information, read the article: Analysis framework: Porter’s Five Forces.

Price taker: a firm that can change its production and sales of a product without significantly affecting the market price.

Product differentiation: the process of describing the differences between a good or service in order to demonstrate the unique aspects of your good or service and create an impression of value in the mind of the consumer.

Public good: a good which is non-rival and non-excludable. Non-rivalry means that consumption of the good by one individual does not reduce availability of the good for other to consume; and non-excludability means that no one can be excluded from using the good. In the real world, there may be no goods which are absolutely non-rival and non-excludable.

Real value: a value adjusted for inflation or deflation. For example, if a Big Mac costs $3 this year and $6 next year, then assuming inflation is 100% the real price of the BigMac has not changed.

Recession: broadly speaking, a recession is a period of slow or negative economic growth, usually accompanied by rising unemployment. Economists have other more precise definitions of a recession, the easiest of which to understand is “two consecutive quarters of falling GDP”. For more information, read the article: Economic recession 2008: measuring the strength of the economy. Alternatively, visit the Economist A-Z.

For more information, read the article: Analysis framework: McKinsey’s 7-S Framework.

SMART Goals: any goal which is Specific, Measureable, Achievable, Relevant, and Time-Bound. For more information, read the article: Set SMART Goals.

Spillover: externalities that result from economic activity and affect people who are not directly involved in the activity. Spillover can be positive or negative. Pollution that leaks out of a manufacturing plant and into a local river would have a negative spillover effect on local fishermen. The beauty of the buildings in Oxford would have a positive spillover effect on locals and tourists.

Substitute goods: any goods for which an increase in demand for one leads to a fall in demand for the other.  Substitute goods represent a form of indirect competition. Examples of substitute goods might include Coca-Cola and Pepsi or Vegemite and Nutella.

Value Chain Analysis: the process of separating a business operation into a series of value-generating activities in order to understand the activities that provide the business with a competitive advantage. For more information, read the article: Analysis framework: Value Chain Analysis

Variable cost: a cost that varies with the quantity of output produced.  When making decisions in the short run, variable costs are the only costs that should be considered because, in the short term, a company cannot change its fixed costs.

Vertical integration: refers to a form of diversification where a firm expands its business to different points in the supply chain. For example taking over a supplier (backwards vertical integration) or taking over a customer (forwards vertical integration).

Backward vertical integration: A company engages in backward vertical integration when it purchases one or more suppliers that produce inputs that the company uses to produce final goods or services. For example, a car company might own a tire company, a glass company, or an engine manufacturer. Benefits of backward vertical integration include (1) creating stable supply, and (2) ensuring a consistent quality of inputs.

Walmart Effect: A situation where a single customer becomes the major purchaser of goods and services giving it substantial control of the market.
